BK Series

Kitagawa BK Series

Each of the Kitagawa BK Series Kits contains the following components:

  • Pressure Reducing Regulator
  • Flowmeter
  • Flow Bypass Valve
  • Timer
  • Detector Tube Tip Cutter
  • Adjustable Wrench
  • Hard Shell Carrying Case
  • Optional 50ml syringe/tubing for use with Oxygen detector tube

Detector tubes for measuring each of the five breathing air components are sold separately:

  • Carbon Monoxide
  • Carbon Dioxide
  • Oil Mist
  • Water Vapor
  • Oxygen

After connecting the BK assembly to the compressed breathing air source to be analyzed, the breathing air is passed through each detector tube at a specific pressure, flow rate and time interval. Each detector tube is made with high purity reagents that absorb and react with the target component. The reaction causes a colorimetric stain whose length is proportional to the component’s concentration. The actual concentration is read directly from the measurement scale printed on the detector tube.
  • Complete analysis for five components within minutes; no need to wait for lab results
  • Connects directly to the breathing air source
  • No need for electrical power or batteries
  • Easily transported in carrying case
  • Very economical
  • Backed by a one year warranty
The Kitagawa BK Series is ideal for anyone involved in the filling, purification, generation, or usage of compressed breathing air. Impurities in breathing air can adversely affect human health. The BK Series is designed to measure these contaminants in SCBA, SCUBA and other pressurized breathing air cylinders, as well as directly from the outlet of an air compressor or purifier. The BK easily measures five components within minutes: carbon monoxide, carbon dioxide, oil mist, water vapor and oxygen.
